VISE OR THE LIKE.

SPECIFICATION forming part of Letters Patent No. 763,226, dated June 21, 1904.

Application filed September l0, 1903. Serial No. 172,645. (No model.)

To all whom it may concern,.- j

Be it known that I, FREDERICK E. VALDEN, a citizen of the United States, and a resident of Worcester, in the county of Worcester and State of Massachusetts, have invented new and useful Improvements in Vises or the Like, of which the following is a specification.

My invention relates particularly to vises, but is applicable also to other work-holders.

The object of my invention is to provide a compact and strong vise whose two jaws can be adjusted relatively to engage or disengage the work with ease and rapidity. The ordinary bench-vise comprises a fixed jaw having a base adapted to be fixed to the bench and a movable jaw Inounted to slide on the base of the fixed jaw. The movable jaw carries a screw engaging a socket in the fixed jaw, and by means of this screw the two jaws are moved relatively to engage or disengage the work. In order to secure the requisite power, the pitch to the screw was necessarily small, and therefore considerable time was required to open or close the jaws, and this has been an important objection to vises as heretofore constructed which it is the object of my invention to remove.

My improved vise comprises two relatively movable jaws, one carrying a screw engaging a threaded socket on the other jaw. The threads of the screw and socket, however, are segmental in form and arranged in one or more longitudinal rows,so that when the screw and socket occupy one relative angular posif tion the thread-sections of the screw engage and cooperate with the thread-sections of the socket and the two jaws are locked together; but when the screw and socket occupy another relative angular position the thread-sections of thescrew do not engage the thread-sections of the socket and the two jaws are notlocked together, but are free to be adjusted toward and from each other without operating the screw.

In the best form of my invention the socket is made in two parts in line with each other axially, each part being made with a row of segmental thread-sections. These two parts of the socket are relatively rotatable, so that the thread-sections of one may be brought into line with the thread-sections of the other, and by positioning the screw angularly on its axis its thread-sections may be disengaged from the thread-sections of botlrparts of the sockets, or the two parts may be turned relassY vise embodying one form of my invention.

Fig. 2 is a rear elevation of the vise shown in Fig. 1. Fig. 3 is a cross-sectional view of the screw hereinafter described. Fig. 4 is acrosssectional view of the fixed section of the socket hereinafter described.

Having reference to the drawings, A represents the fixed jaw of a bench-vise, which is made with a base a, adapted to be fastened to a bench or other support, and with a bearing to receive the stem of a movable jaw B. The movable jaw B carries a screw b', provided with the usual operating-handle b2. The screw b is made with two diametrically opposed longitudinal rows of segmental threads or thread-sections b3, separated so as to leave be- 8O tween them two longitudinal passage-ways b4. Within base a is arranged a socket C, hereIn shown as made in two parts c and c. The part o of the socket is fastened rigidly to base a by screws c2, and the part c is a sleeve jourextent by two stops and c, projecting from base a.

The part c, as shown in Fig. 4, is made with two diametrically opposed longitudinal rows of seg'mental threads or thread-sections c7, separated so as to leave between them two longitudinal )assaOe-wajsc while the part c is made with two diametrically opposed longitudinal rows of segmental threads or threadsections c, separated so as to leave between them two longitudinal passage-ways esl.

Vhen handle c" on part c is against stop c", the two rows of threads c on part c' are directly in line with the two rows of threads 07 on part c, and, as will now be obvious, if screw be so positioned that its two rows of threads b3 are in the two passage-ways 08 of part c and 081 of section eL-that is, between the two rows of threads of both parts of the socketCsaid screw will be'wholly disengaged from both parts of socket C and jaw B will be free to be moved quickly toward and from jaw A. Vhen, however, handle o* on section c is against stop c5, the two rows of threads c on part c are staggered with relation to the two rows of threads c7 on part c--that is, the rows c of part 0/ are in line with the passage-ways o of part c so that into whatever angular position screw may be turned its segmental threads are always in engagement with thc threads of onel part or the other of the socket. Therefore when handle c'L is against stop c5 and screw is rotated jaw B is moved by the screw toward and from the liXed jaw A.

To clamp a piece of work in the vise, handle a is moved into position against stop c, which frees jaw B, and then said jaw is shoved quickly up against the work. Handle c* is then moved from stop c over against stop C, after which screw b' is rotated in a direction to cause the jaws A and B to pinch onto the work. lt will be observed that the friction between the threads of screw 7) and the threads oi' sections c' during this operation tends to hold handle cl against stop c. When the work is to be removed from the vise, handle cL is thrown down against stop c, thereby instantly freeing the work it' the thread-sections ?)3 of screw c' are in the passage-ways 08 of part c, or, if not, as soon as screw L is turned far enough to bring its thread-sections into those passage-ways c7 the work will be freed. In this way the work may be inserted in the vise or removed quickly and with ease.

Vhile I have herein shown and described my invention as embodied in a bench-vise, it is to be understood that it is applicable also to other kinds of work-holders or the like comprising two or more relatively movable jaws.

What I claim isl. In a vise or the like, a pair of relatively movable jaws; a rotatable screw on one or' said jaws made with a longitudinal row of segmental thread-sections, and a socket on the other jaw made in two relatively adjustable parts, each part being made with a longitudinal row of segmental thread-sections for engaging the thread-sections of the screw.

2. In a vise or the like, a pair of relatively movable jaws; a rotatable screw on one of said jaws made with a longitudinal row of segmental thread-sections; a socket on the other jaw made in two relatively adjustable parts, each part being made with a longitudinal row of segmental thread-sections for engaging the thread-sections of the screw, and a stop for limiting relative movement of the two parts of the socket in one direction.

3. In a vise or the like, a pair of relatively movable jaws; a rotatable screw on one of said jaws made with a longitudinal row of segmental thread-sections; a socket on the other jaw made in two relatively adjustable parts, each part being made with a longitudinal row of segmental thread-sections for engaging the thread-sections oi' the screw, and stops for limiti ng relative movement between the two parts of the socket in both directions.

4. In a vise or the like, a pair oi' relatively movable jaws; a rotatable screw on one of said jaws made with a longitudinal row oi' segmental thread-sections; a socket on the other jaw made in two parts one of which is rotatable, each of said parts being made with a longitudinal row of segmental thread-sections for engaging the thread-sections of the screw; and a handle connected with the rotatable part of the socket.

5. In a vise or the like, a pair of relatively movable jaws; a rotatable screw on one of said jaws made with two diametrically opposed rows ot' segmental thread-sections separated by longitudinal passage-ways; a socket on the other jaw made in two parts, one of which is rotatable, each of said parts being made with two longitudinal rows of segmental threadsections separated by longitudinal passageways.

6. In a vise or the like, a pair of relatively movable jaws; a rotatable screw on one of said jaws made with two diametrically opposed rows or' segmental thread-sections separated by longitudinal passage-ways; a socket on the other jaw made in two parts one of which is rotatable, each of said parts being made with two longitudinal rows of segmental threadsections separated by longitudinal passageways, and stops for positioning the rotatable part of the socket relatively to the other part.
